Abstract: The present invention relates to an organic light emitting diode display device capable of sensing driving current of each pixel with a simple configuration to compensate for a luminance deviation between pixels and a pixel current sensing method thereof. The organic light emitting diode display device includes a display panel including 2N (N being a natural number) pixels that share a reference line though which a reference signal is supplied and are respectively connected to 2N data lines through which data signals are applied, and a data driver for driving the 2N pixels sharing the reference line in a time division manner through the data lines, sensing currents of the time-division-driven 2N pixels as voltages through the shared reference line and outputting the sensed currents, in a sensing mode.
